NAME
ipa-replica-install - Create an IPA replica
SYNOPSIS
DOMAIN LEVEL 0
ipa-replica-install [OPTION]... replica_file
DOMAIN LEVEL 1
ipa-replica-install [OPTION]...
DESCRIPTION
Configures a new IPA server that is a replica of the server. Once it has been created it is an exact copy
of the original IPA server and is an equal master. Changes made to any master are automatically
replicated to other masters.
To create a replica in a domain at domain level 0, you need to provide an replica file. The replica_file
is created using the ipa-replica-prepare utility.
To create a replica in a domain at domain level 1, you don't have to provide a replica file, the machine
only needs to be enrolled in the FreeIPA domain first. This process of turning the IPA client into a
replica is also referred to as replica promotion.
If you're starting with an existing IPA client, simply run ipa-replica-install to have it promoted into a
replica.
To promote a blank machine into a replica, you have two options, you can either run ipa-client-install in
a separate step, or pass the enrollment related options to the ipa-replica-install (see DOMAIN LEVEL 1
CLIENT ENROLLMENT OPTIONS). In the latter case, ipa-replica-install will join the machine to the IPA
realm automatically and will proceed with the promotion step.
If the installation fails you may need to run ipa-server-install --uninstall and ipa-client-install
before running ipa-replica-install again.
The installation will fail if the host you are installing the replica on exists as a host in IPA or an
existing replication agreement exists (for example, from a previously failed installation).
A replica should only be installed on the same or higher version of IPA on the remote system.
OPTIONS
DOMAIN LEVEL 1 OPTIONS
-P, --principal
The user principal which will be used to promote the client to the replica and enroll the client
itself, if necessary.
-w, --admin-password
The Kerberos password for the given principal.
DOMAIN LEVEL 1 CLIENT ENROLLMENT OPTIONS
To install client and promote it to replica using a host keytab or One Time Password, the host needs to
be a member of ipaservers group. This requires to create a host entry and add it to the host group prior
replica installation.
--server, --domain, --realm options are autodiscovered via DNS records by default.
-p PASSWORD, --password=PASSWORD
One Time Password for joining a machine to the IPA realm.
-k, --keytab
Path to host keytab.
--server
The fully qualified domain name of the IPA server to enroll to.
-n, --domain=DOMAIN
Set the domain name to DOMAIN.
-d, --realm=REALM_NAME
Set the IPA realm name to REALM_NAME.
--hostname
The hostname of this machine (FQDN). If specified, the hostname will be set and the system
configuration will be updated to persist over reboot.
DOMAIN LEVEL 0 OPTIONS
-p PASSWORD, --password=PASSWORD
Directory Manager (existing master) password
-w, --admin-password
Admin user Kerberos password used for connection check
BASIC OPTIONS
--ip-address=IP_ADDRESS
The IP address of this server. If this address does not match the address the host resolves to and
--setup-dns is not selected the installation will fail. If the server hostname is not resolvable,
a record for the hostname and IP_ADDRESS is added to /etc/hosts. This this option can be used
multiple times to specify more IP addresses of the server (e.g. multihomed and/or dualstacked
server).
--mkhomedir
Create home directories for users on their first login
-N, --no-ntp
Do not configure NTP
--no-ui-redirect
Do not automatically redirect to the Web UI.
--ssh-trust-dns
Configure OpenSSH client to trust DNS SSHFP records.
--no-ssh
Do not configure OpenSSH client.
--no-sshd
Do not configure OpenSSH server.
--skip-conncheck
Skip connection check to remote master
-d, --debug
Enable debug logging when more verbose output is needed
-U, --unattended
An unattended installation that will never prompt for user input
--dirsrv-config-file
The path to LDIF file that will be used to modify configuration of dse.ldif during installation of
the directory server instance
CERTIFICATE SYSTEM OPTIONS
--setup-ca
Install and configure a CA on this replica. If a CA is not configured then certificate operations
will be forwarded to a master with a CA installed.
--no-pkinit
Disables pkinit setup steps
--skip-schema-check
Skip check for updated CA DS schema on the remote master
DNS OPTIONS
--setup-dns
Generate a DNS zone if it does not exist already and configure the DNS server. This option
requires that you either specify at least one DNS forwarder through the --forwarder option or use
the --no-forwarders option.
--forwarder=IP_ADDRESS
Add a DNS forwarder to the DNS configuration. You can use this option multiple times to specify
more forwarders, but at least one must be provided, unless the --no-forwarders option is
specified.
--no-forwarders
Do not add any DNS forwarders. Root DNS servers will be used instead.
--auto-forwarders
Add DNS forwarders configured in /etc/resolv.conf to the list of forwarders used by IPA DNS.
--reverse-zone=REVERSE_ZONE
The reverse DNS zone to use. This option can be used multiple times to specify multiple reverse
zones.
--no-reverse
Do not create new reverse DNS zone. If a reverse DNS zone already exists for the subnet, it will
be used.
--no-host-dns
Do not use DNS for hostname lookup during installation
--no-dns-sshfp
Do not automatically create DNS SSHFP records.
--no-dnssec-validation
Disable DNSSEC validation on this server.
EXIT STATUS
0 if the command was successful
1 if an error occurred
3 if the host exists in the IPA server or a replication agreement to the remote master already exists
